I. Catalyst development in asymmetric phase transfer catalysis employing QSAR methods II. Computational investigations on the stereochemical course of the addition of allylsilanes to aldehydes
Part I of this dissertation describes the investigation in APTC employing a chemoinformatic analysis of the alkylation of a protected glycine imine with libraries of enantiomerically enriched quaternary ammonium ions. The synthesis of the quaternary ammonium ions follows a diversity oriented …

Neue optisch aktive Phosphoniumsalze als Phasentransferkatalysatoren sowie die Verwendung der korrespondierenden Phosphane in der asymmetrischen Katalyse
… of optically active phosphoniumsalts in asymmetric phase transfer catalysis is described. Emphasis is placed on the Darzens-reaction of benzaldehyde and chloroacetophenone. First, achiral phosphoniumsalts were used under variation of the structure of the salt, temperature, reaction time …

Phase transfer catalysis: catalyst screening, reaction development, and mechanism analysis
The asymmetric alkylation of a glycine Schiff base in addition to the development of a [2,3]-Wittig rearrangement under phase transfer catalysis (PTC) reaction conditions was investigated. Supplementing these studies, a deeper understanding of the PTC mechanism was sought for the alkylation of …
